Had a quick scoot around and realised they'd all taken the same take. Just seems this was the message jumped on when in reality, it's two different things for a start in relation to particulates and carbon, and it's a tiny piece of the puzzle in any event.
Best I could track down it was more vague wide promises and no substance. Truth is, most wood burning stoves can only burn the kiln dried stuff anyway as it's the only thing that will fit and have some longevity of burn without going out.
So it's not really an issue, someone just got confused somewhere on pallet wood in the countryside being an issue if used in the city (it's not used in the city anyway) lol
